PALUREA: Severe Imported Malaria in Adults (PALUREA)

PALUREA: Severe Falciparum Imported Malaria in Adults: Clinical and Physiopathological Study

Plasmodium falciparum malaria remains a major public health problem in endemic areas, with approximately 2 million deaths each year, especially in tropical African countries.

In non-endemic industrialized areas, imported malaria is generally diagnosed in travelers, as well as immigrants from endemic countries. Such imported cases have increased worldwide, with approximately 7000 cases each year in France. Among these cases, 300 are severe requiring hospitalization in the intensive care unit (ICU) with an overall mortality rate of 10%, despite available effective care.

Many studies have been performed to evaluate clinical and physiopathological aspects of severe malaria in endemic areas but few data are available for imported malaria. Therefore, determinants of severe imported malaria are not well known. The majority of patients hospitalized in the ICU for severe malaria are white caucasians as well as those patients who die.

The present study has two main objectives:

(i) to describe the clinical spectrum of severe imported malaria and to assess outcome (mortality and neurological sequelae), and the biological interactions between host and the parasite,

(ii) to evaluate the role of gene polymorphisms, of parasitic factors in the occurrence of severe malaria with a case control study comparing severe and non-severe malaria in patients matched according to ethnic patterns. The intensity of the inflammatory response will also be studied in the two groups of patients.

Study Overview

Detailed Description

Plasmodium falciparum malaria remains a major public health problem in endemic areas, with approximately 2 million deaths each year, especially in tropical African countries.

In non-endemic industrialized areas, imported malaria is generally diagnosed in travelers, as well as immigrants from endemic countries. Such imported cases have increased worldwide, with approximately 7000 cases each year in France. Among these cases, 300 are severe requiring hospitalization in ICU with an overall mortality rate of 10%, despite available effective care.

Many studies have been performed to evaluate clinical and physiopathological aspects of severe malaria in endemic areas but few data are available for imported malaria. Therefore, determinants of severe imported malaria are not well known. The majority of patients hospitalized in ICU for severe imported malaria are white caucasians, as well as those patients who die.

The present two-year prospective multicentric nationwide study has two main objectives:

  1. To describe the clinical spectrum of severe imported malaria in France and to assess outcome (especially mortality, very severe cases, and neurological sequelae).
  2. To analyse the biological interactions between host and the parasite, by evaluating: the role of gene polymorphisms of the host including haemoglobin analysis, the intensity of inflammatory response, endothelial activation, and finally several plasmodial factors.

We hope to include 150 to 200 patients with severe malaria hospitalized in ICU and 150 to 200 patients with uncomplicated malaria. These two groups will be included in a case control study comparing severe and non-severe malaria with matching according to ethnic patterns.
